Sap Curses are prayers from the Ancient Curses prayer book. Players need to have completed The Temple at Senntisten to access these prayers. Once players have completed the quest, they can switch to the Ancient Curses prayer book by praying at the Altar of Zaros in the Zarosian temple beneath the Digsite. The Sap curses drain the player's opponent chosen attack style by 10%. This will increase to 20% over time. When the curse is deactivated, the initial 10% that was drained will be immediately restored to your opponent's stat, however, any subsequent drain that had occurred since activation will slowly regenerate over time as usual.
